eennvviirroonnmmeennttaall vvaarriiaabblleess -- Technical Information

The _e_n_v_i_r_o_n_m_e_n_t is  a set of information that is  read by all programs that
run on  your system.   It consists of  one or more  _e_n_v_i_r_o_n_m_e_n_t_a_l _v_a_r_i_a_b_l_e_s
that you  set.  For example, when you set  the environmental variable PPAATTHH,
you tell COHERENT that you wish to pass this information to all programs on
your system, including COHERENT itself.

By changing the environment, you can change the way a command works without
rewriting any commands that you  may have embedded in batch files, scripts,
or mmaakkeeffiillees.

Your programs may  request environmental variables of their own definition.
COHERENT uses the following environmental variables to set its environment.
Note that the  variables marked with an asterisk are  used only by the Korn
shell kksshh.

AASSKKCCCC....... Have mmaaiill prompt for CC names

You  can also  set  the following  environmental variables  to control  the
default settings of  the COHERENT assembler aass, the C  compiler cccc, and the
linker lldd:

AARRHHEEAADD...... Append options to beginning of aarr command line
AARRTTAAIILL...... Append options to end of aarr command line
AASSHHEEAADD...... Append options to beginning of aass command line
AASSTTAAIILL...... Append options to end of aass command line
CCCCHHEEAADD...... Append options to beginning of cccc command line
